2 Claims.

This invention relates to an ear ornament and the method of making thesame, or more particularly to the finding for an ear ornament.

In the making of ear ornaments it is usual to provide from tubular stocka short section which is internally threaded for the reception of thebinding screw. This section is then soldered to a U-shaped portion ofthe ear wire as a separate'assembly operation. Soldering is an expensiveoperation and one which requires considerable skill.

One of the objects of this invention is to provide the U-shaped portionof the ear wire and the threaded portion which receives the biddingscrew without the necessity of soldering.

Another object of this invention is to provide the U -sh.aped bodyportion and the portion which receives the binding screw piece so thatsoldering will be unnecessary and the parts will be strong and withoutjoint.

Another object of this invention is to eliminate certain assemblyoperations.

Another object of this invention is to eliminate the necessity ofcutting plated stock to provide the portion which receives the bindingscrew thus enabling the plating of the stock to cover all edges.

Another object of this invention is to provide an ear wire by such amethod that no raw edges which come from cutting the stock will beprovided, thus enabling the ear wire to be formed from plated stock withall parts or edges covered with the plate which goes to form the stock.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is an elevation illustrating the finished article which is madeby the method of this invention;

Fig. 2 is a perspective view illustrating a U- shaped length of wireprior to any operations except that of bending being performed thereon;

Fig. 3 is a perspective view showing the end of the wire as flattened;

Fig. 4 is a perspective view showing the flattened end as partially bentinto cylindrical shape;

Fig. 5 is a perspective view of the flattened portion bent intocylindrical shape;

Fig. 6 is a view similar to Fig. 5, illustrating a tapas being passedthrough the cylindrical portion;

Fig. 7 is a view similar to Fig. 5, illustrating the binding screw asplaced in the cylindrical thread- 2 ed portion and as having one headassembled thereon;

Fig. 8 is a view similar to Fig. 7 but showing in section the other headof the binding screw as mounted thereon.

In proceeding with this invention I provide a length of wire and flattenand roll one end of it into cylindrical shape and then thread thisportion for the reception of the binding screw. This eliminates thenecessity of providing a separate part and soldering it onto the wire.The finding in this form may then be utilized as heretofore for theassembly of an ornament thereon, {and the mounting of the binding screwin posiion.

With reference to the drawings, in designates a length of cylindricalwire which has been bent into U-shape providing a short leg I l and alonger leg I2. The longer leg I2 is swedged as at l3 (see Fig. 3) so asto flatten the same and after this flattening the flattened portion i3is annealed. A first rolling as at H (see Fig. 4) is provided so thatthis flattened portion I3 will extend partially about a cylindricalform. The next operation is swedging or rolling, which bends theflattened portion as at l5 (see Fig. 5) into cylindrical form, andthereafter the inner surface It of this cylindrical form is tapped as bya tap H, as shown in Fig. 6.

After the finding has been formed, such as on completion of tapping asshown in Fig. 6, a binding screw I8 as shown in Fig. 7 having one headi9 previously assembled thereon is threaded into the cylindrical tappedportion 15 as shown in Fig. 7 and thereafter a larger head 20 whichserves as a handle is assembled on the other end of the screw l8 asshown in Fig. 8. Any ornament such as 2| (see Fig. 1) is assembled onthe short arm I l of the ear wire so as to provide the same of anornamental appearance. The ornament will have a jaw portion 22 whichwill be positioned axially opposite the head i9 and the lobe of the carmay be positioned between the portions I9 and '22 and by turning thehandle head 20 the screw l8 will be moved so as to engage the lobe ofthe ear and bind the ornament 2| thereon.

I claim:

1. The method of forming a finding for an ear wire comprising providinga length of plated wire cylindrical in cross section, flattening one endportion of said wire, rolling the flattened portion about an axistransverse to said wire and parallel to the flattened surface intocylindrical shape with the end at the juncture of the cylin- REFERENCESCITED The following references are of record in the file of this patent:
